Find the sum of all integers between −102 and 104.
lions [1.4K]
Technically, you could go through and add every single integer between -102 and 104, but that is a lot of work.

However, there is a shortcut.

The opposite of -102 is 102, right? When you add two opposites together, they turn out to be 0. You can use this for every integer from -102 to 102.

Basically, you end up with 103 and 104 that are left.

Add them and you get 103+104=207.

207 is the answer.

If four times a number plus 3 is 11, what is the number?
Morgarella [4.7K]
The number is 2 

To find the answer set the problem up like this:

4X + 3 = 11

Now, solve for X.
Whatever you do to one side of the = sign, do to the other side.
Take 3 away from both sides: 4x = 8
<span>Now divide both sides by 4: x = 2
